Summary

& Heck, A. Dam in Missouri is a privately-owned structure primarily used for recreational purposes. Completed in 1965, this earth dam stands at a height of 16 feet and has a storage capacity of 43 acre-feet. Situated in Crawford County, the dam is located in close proximity to the tributary to Shoal Creek, offering a picturesque setting for outdoor enthusiasts.

Despite its recreational focus, the Haas, R. & Heck, A. Dam poses a high hazard potential and has not been rated for condition assessment. The last inspection took place in 1979, highlighting the need for updated safety evaluations to mitigate any potential risks. With no state jurisdiction or regulation, it is crucial for the private owners to prioritize maintenance and emergency preparedness to ensure the safety of the surrounding community.

As water resource and climate enthusiasts explore the data surrounding this dam, it serves as a reminder of the importance of ongoing monitoring and maintenance for infrastructure in potentially hazardous areas. With its scenic location and significant storage capacity, the Haas, R. & Heck, A. Dam presents both recreational opportunities and potential risks that must be carefully managed to safeguard both the environment and public safety.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
